摘　　要：根据船舶动力学的基本理论,分析计算在工作环境下7500t特大型浮吊所受到波浪载荷作用情况.以海况等级5,蒲福风级5级,波高2ζa=1.4m,平均周期Tz=5.4s工作环境为例,分析计算横向及纵向波浪对7500t浮吊的垂荡干扰力、干扰力矩及横漂力,并为7500t特大型浮吊的抗倾覆稳定性计算提供基础理论数据.On the basis of ship dynamical principles, wave loading conditions are initially analyzed for the 7 500 t ultra-large-scale floating cranes. Under such circumstances as the 5^th oceanic condition, the 5^th Puford wind, 1. 4 meter wave height and 5.4 second wave period, the perpendicular disturbance force-torque and crosswise drifting force are next calculated based on the horizontal and vertical waves. Eventually, this approach paves a venue for anti-overturn stability calculation.
